This opens path to per-reporter colour output customization, and fixes multiple issues with the old colour implementation. Under the old implementation, using Win32-backed colouring would always change the colour used by the console, even if the actual output was written elsewhere, such as a file passed by the `--out` flag. This will no longer happen, as the reporter's colour impl will check that the reporter's stream is pointed to console before trying to change the colours. POSIX/ANSI colour implementation suffered a similar-ish issue, in that it only wrote the colour escape codes into the default output stream, even if the reporter asking for colouring was actually writing to a completely different output stream.
What's the Catch2?
Catch2 is mainly a unit testing framework for C++, but it also provides basic micro-benchmarking features, and simple BDD macros.
Catch2's main advantage is that using it is both simple and natural. Tests autoregister themselves and do not have to be named with valid identifiers, assertions look like normal C++ code, and sections provide a nice way to share set-up and tear-down code in tests.
Catch2 v3 is being developed!
You are on the devel branch, where the next major version, v3, of
Catch2 is being developed. As it is a significant rework, you will
find that parts of this documentation are likely still stuck on v2.
For stable (and documentation-matching) version of Catch2, go to the
v2.x branch.
For migrating from the v2 releases to v3, you should look at our documentation. It provides a simple guidelines on getting started, and collects most common migration problems.
